DESCRIPTION

The M54/74HCT125/126 are high speed CMOS

QUAD BUS BUFFER (3-STATE) FABRICATED IN

SILICON GATE C²MOS technology. They have the

same high speed performance ofLSTTL combined

with true CMOS low power consumption. These de-

vices require the same 3-STATE control input G to

be takenhigh to make the output go into the high im-

pedance state.This integrated circuit has input and

output characteristics that are fully compatible with

54/74 LSTTL logic families. M54/74HCT devices

are designed to directly interface HSC²MOS sys-

tems with TTL and NMOS components. They are

also plug in replacements for LSTTL devices giving

a reduction of power consumption. All inputs are

equipped with protection circuits against static dis-

charge and transient excess voltage.
